l CONTINUOUS EXTRACTOR.

Specification of Letters Patent.

Application led July 6, 1920. Serial No. 394,113.

To all whom zt may concern:

Be it known that I, LLOYD T. MURPHY, a citizen of the United States, and a resident of the city of St. Marys, in the county of Auglaize and State of Chio, have invented certain new and useful Improvements in Continuous Extractors, of which the followby centrifugal force from -the beater proper,

against al screen, which selectively separates the finished from the unfinished stock.

I by that certain construction and arrange- My invention lies between these two types, regarding it from lone point of view, in view of the fact that I withdraw my stock from the beater by means of centrifugal force, and then separate the fine from the coarse sto-ck in a revolving foraminated cylinder into which the material is fed, and through the meshes of which the finely ground material escapes.

One very great advantage which I gain by my method of operation is that I can employ a current or spray of waterfor cleaning the stock away from the holes in the cylinder, since the difficulty of all machines for 'the above purpose, of which 'I have knowledge, islthat the coarse stock so clogs the .holes in the extractor that it is difficult to keep them clean enough to give any more than a mere partial-extraction.

I accomplish the objects of my invention ment of parts to be hereinafter more specifically pointed. out and claimed. A

In the drawings, ,l Figure 1 is a top plan vview of my machine.

Figure 2 is a perspective view of the same. The vOrdinar beater tub is shown at 1, in which is t e beater having a shaft 2 covered by the hood 3.v The beater is driven by a belt operating over a pulley wheel 4, or b any other desired means.

T e hood opens at the end which will r ceive the4 centrifugally thrown stock from the beater, and at this point is set a box 5, the shape. of which is preferably triangular and terminates in a mouth 6. The top 7 of the box has a handle 8 and is preferably renlpvablebfor, purposes of inspection and the The base of the box slopes downwardly so as to carry the materia-l flung from lthe beater'by its centrifuga-l action to a cylinder 9, hav1ng a series of holes therein as at 10, and havlng` preferably heavy rims 11, which extend, beyond the face of the cylinder proper. This cylinder is mounted on suitable bearings and rests on a revolving device'made up of rollers 18, there being two shafts 14, with a roller at each end of each shaft, which rollers drive the cylinder ends around in a frictional manner.

The shafts-14 areequipped with pulleys 15, which are connected by a belt 16 and the tub, where it is fitted with pulleys 17, for being driven off of a pulley 18 on the main shaft of the beater or any other convenlent means.

A1 sprinkler pipe l19 is mounted over the cylinder and directs sprays of water against the foraminated surface thereof, which acts to clear'the holes, and keep them clear of all large material which may adhere therein.

A trough'20 is mounted .beneath'the cylindert and opens upwardly so as to receive material falling through lthe holes of the cylinder. It also extends out at one side of the'cyllnder to catch the materiall flung out rammed May 2,1922.

vone of the shafts extends outwardly from by centrifugal action therein, if any, and its mouth 21 extends out over the side of the beater tub.

Preferably I also provide a. revolving);

shaft22. at the lower end of the mouth' of' the box leading from the beater hood which shaft is revolved by means of a belt 23, and

pulley 24 and acts to feed into the box. the

stringy material which might otherwise clog up the orifice between the box andI the hood.

As so` constructed the mechanlsm operates as l follows The material thrown out by centrifugal force by the beater, which is in itself a partially selected stock is caught by the mouth letting into the closed box. The

revolving shaft at the base of the mouth into this box maintains the mouth clear.

. After flowing by gravity through the box the material falls into the interior of the cylinder, which is constantly revolved by the rollers against which it rests. The spray f of water acts to keep the holes constantly desired In this way the tub may be constantly charge with water and. unbeaten stock, and l' the finished stock will be constantly drawn ofi', so as to-make the beating process a continuous one. p

I'have not attempted to describe in great i detail the various parts of my mechanism,

and advisedly so, because the essential principle may readily be accomplished with various forms of equivalent mechanisms,

which I desire to include within the scope of-my invention.

Having thus described my invention, what ll claim as.`new and desire to secure by Let ters Patent, is

' 1. In combination with a beater and-a tub,

a box for catching the material thrown by centrifugal forceV from the beater, and a revolving cylinder into which the box empties, 'said cylinder having a foraminated body, for the purpose described.

2. In combination with a beaterand a tub and. a hood over the beater, of a closed box letting into the hood-over the beater, and

adapted to catch and conduct'away material thrown by centrifugal force from the beater,

' and foraminated means. in communication with the box for' selectively removing the ne stock from the material and conducting it away from the tub.

.l In combination with a beater and a tub and a hood over the beater, oli a closed box letting into the hood over the beater, and adapted to catch and conduct away material thrown by centrifugal force from the beater,

and: foraminated means in communication with ythe -box for selectively removing the tine stock from the material and conducting it away from the tub, said means comprising a cylinder suitably revolved, said cylinder having a trough set to catch the line material and open at its end to pour the coarse material back into the tub.

4. In vcombination with a beater and a tub anda hood over the beater, of a closed box .letting into the hood over`the beater, and

adaptedto catch and conduct away mate-rial thrown by centrifugal force, from the beater, and foraminated means in communication with the box for selectively removing the fine stock from the material and conducting it4 away from. the tub, said foraminated means having a water spray device for cleaning t-he holes thereof. l

5. ln combination with a beater and a tub and a hood over the beater, of a closed box letting into the hood over the beater, and adapted to catch and conduct away material thrown by centrifugal force', from the beater, and foraminated means in communication with lthe box for selectively removing the fine stock from the material and conducting it away from,` the tub, comprising a revolving shaft set at the lower end of the said entrance.

6. ln combination with a beater and a tub and a hood over the beater, ota closed box letting into the hood over the beater, and 'adapted to catch and conduct away material thrown by centrifugal force, from the beater, and foraminatedl means in communication with the box for selectively removing the fine stock from the material and conducting it away from the tub, comprising a revolvin shaft set at the lower .en-d of the sai entrance.

7. ln combination with a'beater and a tub and a hood over the beater, 'of a closed box letting into the hood over the beater, and adaptedto catch and conduct away material thrown by centrifugal force from the beater, and foramlinated means in communication withthe box for selectively removing the fine stock from the material and conducting it away from the tub, said means comprising a cylinder 'suitably revolved, said cylinder having a trough set to catch the fine mate-v rial and open at its end to pour the coarse .material back into the tub, and havin a Water pipe extending across it, adapte to send spra s of water thereagalnst to clear, the 'foraminated portions thereof.
